Casebook, Episode III – Snake in the Grass Walkthrough

Welcome to Gamezebo’s walkthrough for Casebook Episode 3: Snake in the Grass.

Tips & Tricks

Before embarking on this new mystery adventure, there are a few tips and tricks I’d like to point out.

1. When in doubt, use the "i" key. If you ever get stuck, don’t know where to go next, or just can’t seem to find a particular piece of evidence, pressing the i key will make a magic eye appear that directs you straight to whatever you’re looking for.

2. What’s the objective? Unfortunately Casebook isn’t very clear on what exact items will help you clear which objectives. Sometimes some objectives may only appear once you’ve achieved them, and other times, they’ll never appear at all. But as long as you gather all the evidence, it doesn’t matter.

3. I can’t find the part of the guide that I need. There’s a simple shortcut you can use. Press Ctrl+F, and a search bar will open in your window. Type in whatever keyword you’re looking for (i.e., Mirror), and the function will direct you directly to that word within the guide.

4. Link your evidence! Whenever you see a red chain link on top of a photo of a piece of evidence, it’s important to link it to the other evidence. You’ll only be able to see the ending of the game once you link all the evidence together. When evidence has been successfully linked, a blue chain link icon will appear on the photo. However, if the red chain link is still there, that means the evidence still needs to be linked to something else. If you follow this guide, you won’t have to worry about missing anything.

Puzzle Guide

The following is a guide to help you understand, recognize, and execute puzzles successfully. If you forget how to do something though, don’t worry: the game will toggle hints and instructions at the top of the screen.

1. Dusting for Prints–

Move the mouse cursor, which has turned into a brush, over the evidence you’re dusting. Doing so will cause the evidence to be dusted. If you find the print, you can also click on it. Once the blue bar is filled at the bottom of the screen, you’ll automatically be moved to the next area.

2. Swabbing for a Sample-

This is probably the easiest of all the puzzles. Simply click on the area or object you’d like to take a sample from. Doing so correctly results in the next puzzle.

3. Using the Centrifuge-

Spin the mouse counter-clockwise around the apparatus until the blue bar at the bottom of the screen is filled.

4. Using the Tweezers-

The mouse cursor will turn into a pair of tweezers. Click on whatever object you’d like to examine or extract.

5. Using the Black Light-

Use the mouse to move the Black Light over an object: click on the area that glows brightly, or differently from the normal purple light.

6. Separating Chromosomes-

The chromosomes will be a greenish color when you begin. Click around the petri dish to move the chromosomes around and away from each other: the goal is to make all of them turn grey. Holding down a mouse click results in stronger movement of the chromosomes.

7. Using the Bunson Burner-

Use the mouse to move the test tube over the burner: you want to fill the bar at the bottom of the screen, and you want it to be a green color. Here’s an example:

8. Identifying Prints

Click on various points in the image to identify prints according to the examples on the left. Here’s an example:

Note: These are the common puzzles in the game which occur multiple times. One time/specific puzzles will be addressed accordingly in the guide.
